Christie attacks Obama on immigration, but won't discuss what he would do

In the Midwest to campaign for Republicans in Iowa, Gov. Christie said he didn't want to encourage children of undocumented immigrants to come to New Jersey. If they come, any assistance would be based on merits. "We'll take every request as it comes based on its merits and make those decisions." He said he doesn't want to encourage it.

Christie, who denies he has made a decision about running for president in 2016, found time to attack President Obama's immigration policies: "Frankly, the administration has done an awful job in securing our border and they need to do that, and I think they've done an awful job in trying to handle this situation."

But when asked what he would do better, Christie decided. "I'm not going to discuss a complicated issue like immigration in a parking lot ... It really deserves a much deeper and more thoughtful conversation than we can have here right now."
